Abstract: An apparatus includes an isolation barrier configured to absorb electromagnetic energy. The isolation barrier includes multiple layers stacked on one another. Each of the multiple layers includes at least one dielectric material, at least one thin-film resistive material carried by the at least one dielectric material, and conductive strips in electrical contact with the at least one thin-film resistive material. The isolation barrier also includes vias through the multiple layers. Multiple ones of the vias are positioned along each of the conductive strips, and the vias electrically couple the conductive strips in the multiple layers to one another. The isolation barrier is configured to guide the electromagnetic energy through the multiple layers to enable absorption of the electromagnetic energy by the at least one thin-film resistive material.

Abstract: A cover for an effector, such as a projectile, missile, or gun-launched effector, includes two parts that are translatable relative to one another, such that the cover separates in stages as the effector launches. The cover includes an outer cover portion that is made up of multiple outer cover segments that together define a central opening through which part of an inner cover portion extends. In a launch of the effector, the effector first makes contact with the inner cover portion. This pushes the inner cover portion forward, breaking the attachment with the outer cover portion, and allowing the inner cover portion to translated forward relative to the outer cover portion. As the inner cover portion translates forward relative to the outer cover portion, the inner cover portion eventually makes contact with the outer cover portion, with both being pushed forward, and separating from the launcher.

Abstract: A lift cart includes a lift table that moves between a raised position and a lowest position and a braking device attached to the lift cart. A braking device includes an actuator, a linkage bar, and a first brake assembly. The linkage bar connects to the actuator. The linkage bar translates in a first direction upon activation of the actuator. The first brake assembly connects to the linkage bar. The first brake assembly moves from a deployed state to a retracted state as the linkage bar translates in the first direction.

Abstract: A two-phased liquid-cooled electrical power apparatus includes a plurality of cooling circuits that recirculate and transition respective engineered fluids between liquid and vapor states around closed-loop fluid paths to cool a plurality of devices. A portion of each fluid path is either integrated with or in thermal contact with its device. The engineered fluids are evaporated within the respective portions of the fluid paths to hold the operating temperatures at or near the respective and different phase transition temperatures. The cooling circuits may be used to maintain different operating temperatures of hollow primary and secondary winding coils in a power transformer, of parallel connect hollow winding excitation coils and a common magnetic core in an electrical reactor, of power semiconductor devices mounted on heat sink(s) in which the fluid paths are embedded or power semiconductor devices in which the respective fluid paths pass through the devices.

Abstract: A method includes obtaining thermal energy from a structure to be cooled, where the structure includes micro-channels. The method also includes providing the thermal energy to a water-based polymer network, where the water-based polymer network includes a gel formed using a polymer and water. The method further includes generating one or more gases by heating the water-based polymer network, where generating the one or more gases includes releasing the water in the water-based polymer network to produce steam. In addition, the method includes passing the one or more gases through the micro-channels to remove at least some of the thermal energy from the structure.
